Logan Campbell is the founder and CEO of Aerotas. He began his career as a statistician and, in 2014, went on to found Aerotas, which provides drone photogrammetry and CAD drafting services to land surveyors. Campbell holds an MBA from Harvard Business School and is a Certified Mapping Scientist - UAS by the American Society for Photogrammetry and Remote Sensing (ASPRS). As a recognized industry expert, he regularly speaks at survey and drone conferences, and regularly writes in various land surveying publications.
While the number of surveyors who use drones continues to grow, there are still a handful of questions that keep cropping up at almost every survey conference.
It takes a lot of skill to get survey-grade accuracy using a drone. Ensuring accuracy also requires using ASPRS standards for measuring and verifying the accuracy of the final data.
When using a drone for photogrammetry, one of the most essential data processing steps is to make sure that the orthophoto and 3D model that are produced are accurately georeferenced. There are three main ways to do this.
POB asked Aerotas’ Daniel Katz and Logan Campbell for their thoughts on the strengths and weaknesses of the different tools that make up an unmanned aerial system. This column is part one of a series on evaluating drone tools and technologies for surveyors.
In critical post-fire surveying, having an effective drone program offers several key benefits: reducing survey turnaround time, providing high-resolution imagery to accompany surveys, and minimizing crew exposure to hazards. All of this leads to reconstruction happening faster, cheaper, and safer.
Making sure that a drone is providing as much benefit as possible is crucial as surveyors nationwide face the critical need to do more work faster to keep up with demand.
